While I understand it is an old ritual, I do like that hy asked both father's. My family adores hym and we are all close as is, but I think it just made it go smoother, if that makes sense? No surprises, no omgwtfnooooo responses.. Of course, it dampened the moment when I went to tell my family and they all said "Yep we know!"
I asked hym what hy would of said had either one of our father's said no, and hy said hy would not have asked me then, hy would of proved hy was worthy of marrying me. I thought that was pretty sweet

(Of course, I would of said yes regardless!)
All in all I suppose I see it as a way of making sure everyone is on the same page and accepting, at least in our case. That, and I did not have to tell my extended family - my mom did that
